ACRYLIC FILTER Marine Blue

AMMO of Mig Jimenez Acrylic Filter Marine Blue

A filter is the gentlest of the weathering steps: it neither makes dirt nor brings out the engraved lines, it only shifts the tone of the surface you lay it on. This one has the blue Marine Blue shade. It is used above all where a surface is meant to look cooler and deeper, or where several panels shaded separately need to be pulled together into one whole.

Fixing: why a filter is sealed with varnish

A finished filter is a thin layer on the surface, and the next weathering step can easily dissolve or wipe it away. When a wash, a pigment or dry-brushing comes after the filter, you risk erasing your own work. That is why a filter is sealed with a coat of varnish once it is dry, matte if the surface is to be final, gloss if decals are still to come. The varnish also separates the chemistry of the individual layers, so that afterwards you can safely use a wash with a different thinner without the two mixing. Spray the varnish as a thin mist from a greater distance; a heavy first coat will ripple a fresh filter.

Use

• Stir the bottle thoroughly before laying it on
• Lay the filter on with a soft flat brush in a thin coat and wipe the surplus away
• Let the surface dry completely, and only then move on to fixing, because varnish laid into a damp filter will smear it
• Give the fixing varnish first as a thin mist, and a full coat only once that has gone tacky
• Only on the fixed surface carry on with washes, pigments or further effects

Who it is for

For modelers who build their weathering up in several steps and want to be sure that the individual layers will not disturb one another. Fixing adds work, but it is the most reliable safeguard against the last step destroying all the earlier ones.

Keep out of the reach of children. Work in a ventilated room, protect your eyes and skin and wash your hands after work. Close the bottle carefully after use.
